What I meant whas that you could implement it like

Procedure  TControl.SetLeft (Value : Integer);

begin
  SetBounds(Value,FTop,FRight,FBottom);
  FLeft:=Value;
end;

This way the code is reduced to a minimum. In the event GTK changes, or
you go to a new toolkit, You only have to adjust SetBounds.
